To access deployed contract inside another contract why do we need an interface of that contract?

To access deployed contract inside of another contract, why do we need an interface of the deployed contract, my question is why we cannot access deployed contract without an interface?

@shakilkhan12 Because in order to interact with that contract EVN needs to understand, what functions that contract has, what these functions take and what they return. So that we can pass and get results according to the types that these functions are taking and giving.
